spcification of Letters Patent.

'Patented Nov. 19, 1918.

Application led April 20, 1918*. Serial No. 229,853.

To all whom t may concaem:

Be it known that I, LULU MAUDE a citizen of the United States, Riverside, in the county of Riverside and State of California, have invented a new and useful Drill Device, is a specification.

This invention relates to a device for facilitating the visual instruction of students, more especially very young children, and an object of the invention is to make provision whereby the teacher o r student may readily produce a varlety of different combinations of letters or other characters CHANCE,

or symbols signifying various sounds or combinations of sounds or other matter that may be visually presented. y

Another object of the invention is to produce a device of this character ofcomparatively great simplicity so that it lewill cost dbut little to 'produce and. so that 1t can be easily operated by the student.

Another object is to create interest 1n and attract the attention of young children to the study of speech. f

The accompanying drawings illustrate the invention:

Figure l is a front view of the device.

Fig. 2 is a sectional elevation on lirib indicated by 2-m2, F ig. 1.

Fig. 3 is a front view of the devic'e omitting the slide.

Fig. 4 is a face view of the slide.

Fig. 5 is a front view of one of the rotative members.

rlhere are provided two relatively rotative members 1, 2 of any suitable contour and shown in the drawings in the form of fiat disks. For convenience of description the member 1 may be termed the lower disk and the member 2 may be termed the upper disk. The. disk 2 is provided with a window 3 which may be located adjacent the margin of said 'disk as shown in the drawings. The member 1 is provided in a circle with separate symbols or characters or with separate groups of symbols or characters. Each separate character or group for convenience of description will be termed an element and is designated by the number 4f. Anyone element may be brought into registration with the window 3 by appropriate relative turning of the members 1,2. In the drawings some of the elements 4 are shown as being numbers and others are in the form of word endings.

residing at of which the followingV formed by cutting The members 1, 2 are suitably connected together for relative rotation and in the instance shown are pivoted at their centers to one another by a suitable rivet 5, or equivalent.

The member 2 is portion in alinement another window 6 desired portion of a slide 7 which is shiftably mounted to move between the rotative members. The slide 7 is guided by suitable means and in the instance shown in the drawlngs for this purpose the window 6 is slots 8 parallel with one another on opposite sides of the pivot 5 and the slide 7 passes through said slots and in front of the portion 9 of the member 2 lying between said slots. The pivot 5 is in the portion 9.

provided at its central with the window 3 with to'expose to view anyA` The 'slide 7 is provided at intervals therel along with any desired separate characters or groups of characters, either of which for Apurposes of description will be termed an Vbeing shown in F ig. 1 and the reverse side in Fig. 4.

In children may be taught, for example, the Sounds of different words by members l, 2 relative to one another so as to expose the letters representing a certain sound or group of sounds, as, for example, ii as inFig. 1. The slide 7 will then be adjusted'so as to successively expose the various letters or groups of letters thereon through the window 6 to complete the spelling of different words beginning with 11. Moving the slide 7 tothe position shown in Fig. 1 exposes the letters ight and these letters, in combination with those exposed to view through the window 3, spell the word"fiight and all together represent the phonograms of the appropriate sounds for the spoken word. By moving the slide 7 into various positions it is readily seen that the element ight on the slide 7 may be caused to register with the element s on the member 1 to spell sight, or the element ake to register to spell sake, and so on with all of the elements on the side of the slide 7 shown in Fig. 1. Thus the phonograms represented by the elements 4, 10 are caused to blend.

Preferably a number of slides 7 will be practical use it is readily seen that thel adjusting the i@ reeeee furnished with each device so as to make 1provision for a comparatively great number oii diierent combinations oi' letters, figures or other signs or characters.

From the foregoing it is readily comprebeaded that the construction makes provision for changing' either one or both of two different elements of e group ot elements so es to spell different words or represent various combinations of figures in multiplication, division, 'addition and Subtraction. l); marking; the member l and slide l' with the appropriate elements the device may be used in teaching Phonetics, numbers, Spelling and may be used as a calendar.

l claim:

l. A drill device comorising relatively rotative members, one of said members haw ing a window to expose to View a portion of the second member and seid second member haring characters on its expos-able portions, the tiret member haring a second Windoii' in alinement with the lirst Window. and a slide shift-able behind the second Window and provided with characters adapted to be brought into registration with the characters exposed through the first Window.

2. drill device comprising ai member provided with various characters each Jorming,l an element, e. second member rotative relative to tbe tiret neined member, and a slide shift-able in the second member and provided with various characters eac-h formingl an element and eac-h element being adapted to be brought into alinement With any one of the first named elements by appropriate relative turning of said menibers and Shifting of the slide.

23. drill device comprising two relatively rotative members, a pivot connecting Said members to one another, one of seid members having' a Window adjacent its margin and having slots on Opposite sides oi the pivot, and a Slide passing through the Slots and extending in front of the pivot.

f-l. :l drill device comprising two relatively rotative members, a pivot connecting said members to one. another, one of said members having a Window adjacent its inargin and haring a second window, and a third member movably mounted with respect to the Second window and adapted to have Successive portions tliereole exposed to uView through said second Window when the third member is moved into different positions.
